A client who had a knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)
The Correct Answer is ["0.6"]
- Medication dose: 30 mg enoxaparin
- Medication concentration: 30 mg per 0.3 mL (prefilled syringe)
- Frequency: Every 12 hours
- Duration: 10 days
Calculation:
- Injections per day: Since the medication is given every 12 hours, the client will receive injections 2 times per day (24 hours / 12 hours/injection).
- Total medication per day: To find the total amount of enoxaparin needed per day, multiply the single injection dose by the number of injections:
Total enoxaparin/day = Dose per injection x Number of injections/day = 30 mg/injection x 2 injections/day = 60 mg/day
- Volume of medication per day: Now, we need to find the volume of solution needed to deliver the total daily dose (60 mg) based on the medication concentration (30 mg/0.3 mL). We can achieve this with a proportion:
Volume (mL) / Total dose (mg) = Concentration (mg/mL)
Volume (mL) = (Total dose (mg) x Concentration (mL/mg)) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = (60 mg x 0.3 mL/mg) / 30 mg/mL
Volume (mL) = 18 mL / 30 mL/mL
Simplifying:
Volume (mL) = 0.6 mL
Therefore, the practical nurse (PN) should administer 0.6 mL of enoxaparin each day.

Related Questions
Correct Answer is ["B","D","E","F"]
Explanation
A. A warning about potential charges for child neglect
This is not appropriate in a pre-discharge education context. The focus should be on providing support and education to prevent future incidents and to help the parents understand the importance of supervision and safety.
B. Information about pool safety
Providing information about pool safety is essential to prevent future drowning incidents. Parents should be educated on supervision, barriers, and emergency response measures like CPR. This helps ensure the child's safety and reduces the risk of similar accidents.
C. Instructions on how to access long-term home care
Long-term home care instructions are unnecessary unless the child has specific ongoing medical needs resulting from the submersion. Since the child is showing only minor signs of impact, this education is not relevant.
D. When to follow up with the child's pediatrician
Clear instructions on when to follow up with the pediatrician ensure ongoing monitoring for any delayed effects of the submersion injury. This follow-up helps address any emerging health concerns and reassures the parents about their child's recovery.
E. Assessment of the parent's coping skills
Assessing the parents' coping skills is important to understand their emotional and psychological state post-incident. This can help identify any need for further support or counseling, ensuring the family is equipped to handle the situation.
F. Contact information for community resources
Providing contact information for community resources offers additional support to the parents, such as access to counseling, parenting classes, or safety courses. This reinforces the safety education provided and ensures the parents have resources to turn to if needed
Correct Answer is B
Explanation
A. A warm sleeping environment may exacerbate pruritus by increasing skin dryness and irritation. Cool, comfortable environments are generally better for clients with pruritus.
B. Keeping fingernails trimmed short helps prevent skin damage and infection caused by scratching. This is a practical and effective measure to manage pruritus.
C. Discouraging the use of skin lubricants is not advisable as they can help soothe and moisturize dry, itchy skin. Emollients and moisturizers are often recommended to manage pruritus.
D. Advising against any type of tub bath is not necessary. Instead, the use of lukewarm baths with added colloidal oatmeal or other soothing agents can help reduce pruritus.
